4.3.2 Installing and Connecting the ECS-EMG to the ECS-SW24
The ECS-SW24 adds 24 switches to the IFP-300ECS and IFP-2100ECS controls for a total of 40.
(with the 16 Non-ECS switches on the ECS-EMG).
Follow these steps to install and connect the ECS-SW24:
1. Open Cabinet door and dead front panel.
2. Remove AC power from the main control panel.
3. Disconnect the backup batteries.
4. Install the ECS-SW24 on the six mounting studs located on the inside of the dead front panel. See
Figure 4-15 for IFP-300ECS or Figure 4-17 for IFP-2100ECS.
5. For the IFP-300ECS, connect one end of the wiring harness (P/N 130398 supplied) to the ECS-
EMG and the other end to the ECS-SW24 as shown in Figure 4-15.
6. For IFP-2100ECS connect one end of the wiring harness (PN 130398 supplied) to the ECS-EMG
and the other end to the P4 connector on the NVCM as shown in Figure 4-16. If two ECS-SW24's
are used, connect one ECS-SW24 to the other ECS-SW24 as shown in Figure 4-17.
7. Secure the switch expander(s) to the dead front panel using the supplied six ¼” Hex nuts.
